static int |
binarySearch(short[] a,
int key)
Searches the specified array of ints for the specified value using the binary search algorithm. |
static boolean |
equals(short[] a,
short[] a2)
Returns true if the two specified arrays of shorts are equal to one another. |
private static int |
med3(short[] x,
int a,
int b,
int c)
Returns the index of the median of the three indexed integers. |
private static void |
rangeCheck(int arrayLen,
int fromIndex,
int toIndex)
Check that fromIndex and toIndex are in range, and throw an appropriate exception if they aren't. |
